Module | Sequel::SQL::NoBooleanInputMethods |
In: |
lib/sequel/sql.rb
|
This module augments the default initalize method for the ComplexExpression subclass it is included in, so that attempting to use boolean input when initializing a NumericExpression or StringExpression results in an error.
Raise an Error if one of the args would be boolean in an SQL context, otherwise call super.
